This doc provides details on the use of the GSD files IO modules for the Profibus Interface in the Communicator series.
This document assumes you have configured the Anybus Communicator as required.

MODULE LAYOUTThe GSD file has multiple IO modules that are added up to equal the total configured size of the Profibus configuration. There are 8 Input and 8 output modules with sizes increasing by powers of two. There is also and additional empty module. The Profibus interface has 16 slots, when adding the Profibus IO interface to a Profibus master all slots need to be filled. The slots need to have either their assigned module, to add up to the configured size or filled with an empty module.
If a ABC4014 configuration has 1 input and 1 output byte when it was added to the master the 1 byte input module would be used in slot 1 while the 1 byte output module would be used in slot 9. The remaining slot would be filled with the empty Module.
For a configuration with 80 input bytes and 2 output bytes the 16 byte input module and 64 byte module would be used for the Input data adding up to 80 bytes. The 16 byte module would be in slot 5 and the 64 byte module in slot 7. The two bytes for the output would be in slot 10. All other slots would be filled with empty modules. It should look something like the following.
